reduced to flour, is mingled with water, forming either _atolle_ or
various kinds of _chicha_. Maize will yield, in very favourable
situations, two or three crops per year; though it is but seldom that
more than one is gathered.

supply.

On Maguey, is an object of great value in the table land of the interior
of Mexico; from this plant is obtained the favourite liquor, the

extirpated, and the juice destined to form the fruit flows into the
cavity thus produced, and is taken out two or three times a day for four
or five months; each day's produce is fermented for ten or fifteen days;
after which the _pulque_ is fit to drink, and before it has travelled in
skins, it is a very pleasant, refreshing liquor, to which the Mexicans
